%X 利用ANSYS提供的参数化设计语言（APDL），建立了一种新型盘状摇头型超声电机定子参数化模型，并进行模态分析、模态识别、节点计算、谐响应分析。借助OPTIMUS优化平台集成该参数化模型，以定子结构尺寸参数作为输入，以超声电机对工作频率、模态混叠、弯曲振幅、定子夹持的综合设计要求作为目标，进行了动力学优化设计，并根据优化结果制作了样机。实验表明：定子工作模态满足了预期的设计要求，试验结果与优化设计结果相符。<br>A parametric finite element model of the stator of a rocking head type disc-shape ultrasonic motor was built with the APDL in ANSYS software. Modal analysis, modal identification, node identification and harmonic response analysis of the stator were carried out based on this model. Then, the model is imported into the OPTIMUS software which is a multidisciplinary optimization platform. For dynamic optimization, the structure sizes were regarded as the optimization variables. Synthesized design requirements such as the operating frequency, model separation, amplitude of driving point and the stator clamping were considered to be the optimization objectives. Finally, a prototype of this USM was fabricated with the results of optimum design. The experimental results showed that the operating mode of the prototype meet the design requirements. Moreover, the experimental results were consistent with the optimized ones
